plz tell​

Answer 1

Answer:

let the number be x

(8/9) ^2 *x = (2/3) ^-3

(2³/3²) ² * x = (2/3) ^-3

2^6/3^4 *x = 3³/2³

x = 3³/2³ *3⁴/2^6

x = 3^7 /2^9

Answer 2

Answer:

(8/9)^2 * X = (2/3)^-3,

=> (64/81) * X = (3/2)^3,

=> X = (27/8) * (81/64),

=> X = 2187/512.

so,we should multiply (2187/512) to (8/9)^2 to get (2/3)^-3
